UPL is doing just fine. So much of goaltending is technique. It's not just sliding around and making saves. He's an idea of what he's doing that he looks better at last year.
He's not over sliding this year. Last year at the WJSS, he was pushing way too hard and not stopping square to the shooter. That's all technique. Push too soft and you won't make it to the shooter. So, a goalie has to learn to use his move slide leg to dig in once he reaches the point he wants to stop. That leg has to come up, exposing the five hole, and then go right back down. The goalie can compensate by adjusting where the stick blade goes.
Think that's easy? Go give it a try. Takes months, if not a full year, of practice to master just that.
When a goalie goes to the post, either stand up or RVH, they have to get their skate inside the post and pad outside the post. For those who haven't ever put on goalie pads, most goalies put slack in the toe tie to create space in between the skate and the bottom of the pad. That tie goes right on the post, allowing the skate to be inside the post, and the pad outside. In the RVH, it's nearly impossible to score along the ice.
That takes about a year to master.
So, I'll type this again: UPL is fine. Leave him in Sudbury, then continue to slowly bring him up. He looks a lot better this year but he's got tons of technique work to do before reaching the NHL. Same with Ullmark.... same with almost every goalie.
